Fermented semi-dried feed for weaned piglets

Abstract

The invention discloses a fermented semi-dried feed for weaned piglets. The fermented semi-dried feed is processed from an energy feed, a protein feed, complex trace elements, multi-vitamins, mineral substances, lactic acid bacteria, saccharomycetes and bacillus subtilis by the steps of mixing evenly and fermenting; the fermented semi-dried feed comprises the following components: corn, wheat bran, 46% swelling soya dregs, concentrated albumen-powder of soybeans, Peru steamed fish, beer yeast powder, lactose, calcium hydrophosphate, mountain flour, edible salt, special core materials for weaned piglets, soya-bean oil, choline and an acidifier; and in addition, composite probiotic liquid is added and mixed with clear water, so that the mixed feed is fermented under the condition that the moisture is kept. Required trace elements, vitamins and beneficial bacteria required by the organism are provided for piglets; the immunocompetence and the disease resistance of the piglets are improved; and the fermented semi-dried feed is good in palatability and high in feeding efficiency, piglet diarrhea rate is low, and the weaned piglets can grow healthily.

Description

technical field [0001] The invention relates to a semi-dry fermented feed technology for weaned suckling pigs, belonging to the technical field of feed. Background technique [0002] When the suckling pig is born, there is only rennet in the stomach, and there is very little pepsin. Because the gastric glands are underdeveloped and lack free hydrochloric acid, pepsin has no activity and cannot digest protein, especially vegetable protein. At this time, only the intestinal glands and pancreas are relatively fully developed, and the activities of trypsin, intestinal amylase and lactase are relatively high, and food is mainly digested in the small intestine. Therefore, newborn piglets can only eat milk, but cannot use plant feed. Another manifestation of the imperfect digestive function of suckling piglets is that the speed of food passing through the digestive tract is particularly fast, and the speed of food entering the stomach is emptied. It takes 1.5 hours at the age of 1...

AI Technical Summary

Problems solved by technology

[0003] The age is 16-19 hours, and rural breeding is weaned at 28-35 days, and the speed of passing through the stomach is very fast. During this period, diarrhea of ​​suckling piglets is easy to occur, which seriously affects the growth of suckling pigs; for this reason, the company developed A kind of semi-dry fermented feed for weaned suckling pigs, which uses easily digestible raw materials and beneficial bacteria for artificial in vitro anaerobic fermentation to maximize the digestibility of the feed, thus solving the problem of diarrhea in suckling pigs during this period
